Discourse and practice of trust in business correspondence
during the early modern period
…a Factor is created by Merchant Letters1
In his influential The Structural Transformation of the Public Sphere, Jürgen
Habermas contrasted medieval business correspondence with the public dissemination of
economic news that began in the late seventeenth century, and defined the latter as more
central to the development of western capitalism.2 Several economic historians, as we’ll see,
have endorsed and substantiated this account. Such a clear cut and hierarchical opposition
between ‘private’ and ‘public’ economic information and its means of dissemination,
however, is fundamentally inadequate to understand commercial practices in early modern
Europe. The content and sources of news relevant to merchants often overlapped with those
used by diplomats, missionaries, travellers and others –and merchants themselves could
simultaneously be missionaries, diplomats, adventurers, pilgrims and other figures of various
sorts. In Counter Reformation Italy, for example, “Lutheran” books were often smuggled by
merchants, and business letters contributed to the spread of heterodox ideas.3 But even if we
restrict our analysis to an economic perspective, we have to dismiss any simplistic and
evolutionary depictions of the relation between business correspondence and economic

newspapers. By illuminating the principal functions of letters exchanged among merchants
involved in long-distance trade, this essay contends that ‘private’ correspondence continued
to play a fundamental role long after the appearance and diffusion of printed periodicals
containing economic information. In so doing, it also throws light on the mercantile culture of
early modern Europe even beyond the chronological period examined in this volume. More
specifically, I will insist on the uniqueness of merchant letters when it came to circulating
information about the aptitude and trustworthiness of distant agents. This argument has
important empirical and theoretical implications because as European commerce expanded
geographically, business organization became more complex. New formal institutions such as
the chartered companies and the stock market emerged. But while individual family firms and
ethnic-religious trading diasporas remained essential protagonists in many branches of
commerce, they were also forced to establish durable economic relations with outsiders.
Business correspondence, as I will demonstrate, was a crucial instrument in the forging and
maintenance of these informal cross-cultural networks, and thus also constitutes a precious
historical source we may use to study a neglected phenomenon.
I. Business correspondence in late medieval and early modern Europe
In the fourteenth century, offering advice on how to succeed in business, an Italian
merchant recommended, ‘You should not postpone tending to your correspondence. Paper is
cheap, and often it brings in good profit.’ And he added, ‘One must know how to keep books
and records; to write and answer letters, which is not a small thing, particularly that of
knowing how to dictate letters.’4 A champion of such recommendations was Francesco son of
Marco Datini (ca. 1335-1410), a textile merchant-producer and banker of Prato (a town near

Florence) whose suppliers and customers extended from Barcelona to Bruges, Lisbon, Sicily
and even further. Thanks to good fortune and his own efforts we have over 126,000 original
commercial letters sent to Datini from 285 different localities, and some 11,000 private letters
exchanged by him and his wife, which also contain economic information.5 To date, this is
the largest collection of business correspondence available to historians of Europe and the
Mediterranean. One, two, even three centuries later, merchants continued to devote a lot of
time and care to letter writing, although not all were as zealous or as fortunate as Datini in
their record-keeping efforts. Simon Ruiz of Medina del Campo received more than 50,000
letters between 1558 and 1598;6 and nearly 80,000 letters were sent to the Roux of Marseilles
from 1728 to 1843.7 For the most part, when studying business correspondence, economic
historians have privileged the medieval over the early modern period in spite of the large
collections of letters that exist for the later period. This preference reflects the importance of
merchant letters in the panorama of sources available to historical investigations about
medieval trade. New economic institutions indeed produced voluminous new types of records
starting from the sixteenth century, but these documents should not obscure the continued
centrality of merchant letters in commercial practices of the time.
Practical and legal reasons account for the persistent importance of business
correspondence in European trade. While merchants became more sedentary and new legal

contracts (such as the commenda) that ensured a more efficient division of labour, risk, and
profit developed in medieval Italy, letters remained the main instruments through which a
merchant could exert control over his agents overseas.8 As European commerce expanded,
commission agency became more and more essential to the conduct of long-distance trade,
and business correspondence attained greater rather than lesser significance. In his Le parfait
négociant (first published in 1675), Jacques Savary warned against the risks of commission
trade. As he put it boldly, ‘qui fait ses affaires par commission va à l’Hôpital en personne’
[those who do business via commission agency go straight to the hospital].9 But the age of
European travelling merchants had progressively faded, and letters become the primary tool
through which webs of commercial relations were woven across space and social groups. In
addition, beginning in the fourteenth century and becoming consistent after the sixteenth,
merchants no longer needed to certify their papers with notaries.10 Letters drafted by
merchants and their employees acquired autonomous legal validity, and this recognition made
merchants’ job simpler and cheaper. Meanwhile, as letters became accepted proof in court,
their language necessarily became more and more formulaic: expressions of gratitude and
friendship, for example, acquired contractual meanings.11
The literature known as ars mercatoria mirrors this process of change in both the
legal and practical functions of business correspondence. Merchant manuals of the fourteenth
and fifteenth centuries rarely mention letter writing, while they list different local units of

measurement, currency values and trading customs more generally.12 From the late sixteenth
century on, specialized letter-writing models appeared in print and commercial treaties began
to devote greater attention to correspondence. The Formulaire de missives, obligations,
quittances, letters de change, d’asseurances… by Gabriel Meurier was published in Antwerp
in 1558, followed in 1576 by Gérard de Vivre’s Lettres missives and Jean Bourlier’s Lettres
communes.13 A century later, such compilations had multiplied and come to include both
booklets addressed to tradesmen, shopkeepers and the educated public, such as John Hill’s
popular The Young Secretary’s Guide: or, A Speedy Help to Learning (first printed in London
in 1680 and issued in its 26th edition in 1754), and more specialized bilingual models of
business letters, such as the Italian-German edition of Matthias Kramer’s Il segretario di
banco (Nuremberg 1693). Il negoziante by Giovanni Domenico Peri, the principal Italian
merchant manual of the seventeenth century, included sketchy instructions on how to write
letters, and referred to the legal standing of business correspondence in the chapter devoted to
‘contracts’.14 In the most famous and widely imitated European commercial manual of the
period, Savary urged all merchants to keep copies of the letters they sent so that they could
submit them as evidence in court or could review what they had previously written their

correspondents. That way, they would be sure to keep their orders and their answers to their
correspondents straight.15
While merchant manuals took notice of the importance of business letters, after the
late sixteenth and more intensively after the mid seventeenth century, new periodical
publications of economic information became available: first single-sheet currents
(containing lists of local prices and exchanges rates), and later more voluminous almanacs
and gazettes.16 These printed materials have provided economic historians with invaluable
information. Michel Morineau, for example, challenged accepted theses concerning the
arrival of American bullion to Europe on the basis of the figures extrapolated from the
Amsterdam gazettes.17 It would, however, be wrong to conclude that economic periodicals
supplanted business letters in the seventeenth and eighteenth centuries as the chief source of
economic information. In spite of progress in postal services as well as in overland and sea
shipping, before railroads, steamship and the telegraph were invented, no significant remedy
existed for slow communication. In the early modern Mediterranean and Atlantic, couriers
became faster and more regular, and freight costs as a norm decreased, but no revolution
occurred in maritime or terrestrial transportation.18 Economic newspapers thus had no

significant advantage over business letters in terms of the rapidity with which they
disseminated information. The public nature of periodicals is usually supposed to have had a
strong impact on market expansion and integration. In practice, though, the publication of
prices, exchange, interest and stock rates had only limited effects. While a variety of small
and medium investors purchased shares in the Dutch and later English East India Companies,
for example, the asymmetry of information between the boards of trustees of these companies
and the general public remained wide –and this asymmetry of information contributed to
keep public debt the favourite speculation of most European investors.19 Gazettes and other
periodical publications brought remarkable innovation in marketing and both retail and whole
sales. David Hancock has shown how London-based merchants took advantage of the
proliferation of newspapers in the first half of the eighteenth century in order to advertise the
arrival of their cargo, the auctioning of their goods, the availability of their ships, and
promote their affairs more generally.20 He has also documented how newspapers were
perhaps more crucial than correspondence in the creation of a wide consumer market for
Madeira wine in North America during the eighteenth century.21
These periodicals, however, were less than efficient when it came to informing agents
about the objective as well as intangible qualities of their distant correspondents, especially
when the latter were neither relatives nor coreligionists. This goal was best fulfilled by
business correspondence. In addition to allowing merchants to deliver orders (purchases,
sales, subscriptions of insurance policies, extensions of credit lines, and so forth) and serve as
proof that such transactions had taken place, letters transferred information among

correspondents on a large variety of topics. Indeed, most letters simply reported facts and
opinions without ordering the completion of any specific transactions.22 The information
transmitted via private business correspondence can be schematically grouped under three
headings. Commodity prices, local units of weight and measures, insurance premia, exchange
rates, descriptions of the quantity and quality of products available in specific towns or
regions, and similar matters are paramount. News concerning political, military and
diplomatic events also abound. Both types of information helped the letters’ recipients to
assess short- and medium-term market fluctuations, and thus facilitated their decision-making
process. But merchant letters also contained a third type of information: about merchants
themselves. This knowledge could be either direct (when, for example, the success or failure
of a certain agent was communicated to correspondents) or indirect (in the sense that letter
exchange was itself a form of recognition of reciprocal trust and esteem or at least tested the
possibility of future collaboration). References to personal and familiar matters in business
correspondence, while sporadic, nevertheless contributed to nourishing social and business
ties. Any ambitious merchant considered expressing his condolences and greetings to
business associates to be part of his duties, and many took up their pens in order to negotiate
things as crucial for their firms as good marriages for their daughters. In addition, bills of
exchange, or references to their standing, were sometimes included in ordinary business
letters. This overlap was due as much to the organization of private credit at the time as to the
inextricable link between individuals’ economic and social credit.23

Writing a friend in 1717, an English trader noted, ‘To support and maintain a man’s
private credit, ‘tis absolutely necessary that the world have a fixed opinion of the honesty and
integrity, as well as the ability of the person…’24 To this aim, private business
correspondence was definitely more adequate than public sources. Not only did it ensure the
secrecy that was helpful to cope with competition and necessary in certain dealings, but more
importantly, it incorporated facts and opinions about fellow businessmen that rarely found
expression in printed materials. If by the early eighteenth century the bankruptcy of large
merchant houses regularly appeared in a special section of most London gazettes, this
information was fairly selective and standardized, and restricted to a local readership. Private
correspondence was the only way that merchants could nuance, diffuse, and update
information regarding the standing of smaller and distant actors. Rich in candid comments
about his competitors and filled with a variety of gossip, the letters that Joshua Johnson sent
from London to his associates in Maryland in the 1770s, at a time when English trade in
North America was the most thriving sector of international commerce, testify to this crucial
function.25 Letters of introduction were thus a common and indispensable tool for a merchant
willing to enter a new market or enlarge his network. Conversely, letters could point to the
failures of correspondents who did not deliver their promises or performed below
expectations. Moreover, the often lamented formulaic prose and repetitive content of business
letters were precisely what account for their effectiveness. More than on the legal
implications of merchant letters, trust built on constant reinforcement that buttered one’s
reputation and the multiple cross-references that correspondence networks were able to
create. A trader often repeated the same information in letters addressed to different agents as

a way of stimulating competition and generating vigilance among them. Despite the
individual character of each letter, business correspondence should actually be read as a
polyphonic conversation rather than a dialogue. In sum, primarily because they conveyed
reputation better than any public information sources, private business letters remained a vital
element in the organization of early modern long-distance trade.
II. Economic historians and merchant letters
Merchant letters have long been a classic source for the study of European economic
history. Scholars have traditionally used them to document the speed of diffusion of
economic information as well as advances in business techniques, including the appearance
of new forms of partnerships or financial and insurance systems.26 Others have relied on
business correspondence to outline what was once called ‘the merchants’ psychology’, that is,
the more or less idealized and typified sociological traits of a social group. In the words of
Robert Lopez and Irving Raymond, there exists ‘no better key to the psychology of the
merchant’ than business correspondence.27 A master of this approach, S.D. Goiten drew from
merchant letters to illustrate the ‘sociological’ rather than ‘economic aspects’ of the overseas
trade conducted by North African Jews in the eleventh and twelfth centuries.28 And

particularly in the 1950s and 1960s, under the sponsorship of Fernand Braudel, various
collections of merchant letters were published with little or no commentary, as if these
apparently transparent primary sources would serve the purpose of a histoire totale of the
merchants’ world.29
More recently, economists and economic historians have returned to study merchant
letters, this time with a focus on the role of information in pre-modern markets. They are now
less preoccupied with the technicalities of its transmission than with its function in creating
solidarities, enforcing contracts and minimizing opportunist behaviours. Merchant letters are
thus examined first of all as the means through which an agent’s ability and honesty was
circulated among his correspondents. The most innovative and influential insights in this
regard have come from economist Avner Greif, who in the last fifteen years has engaged in
theoretical and comparative analysis of the commercial organization of medieval North
African Jews. Informed by game theory, rational choice modelling and the new institutional
economic history, his work examines the ways in which the exchange of information about
an actor’s past conduct creates mechanisms of reputation control among self-interested
individuals. Departing from previous interpretations, Greif concludes that trust among the
group of North African Jews that he considers arose from fear of economic loss rather than
social or ethical sanctions.30 Because his model emphasizes the self-enforcing devices

enacted by the market and takes the individual as the unit of analysis, it could ideally apply to
relations between merchants of different ethnic and religious origin as well. But Greif argues
that these mechanisms of reciprocal monitoring and information transmission did not extend
to members of other communities (something that obviously makes even a sympathetic
reader suspicious of the sharp distinction Greif makes between economic and cultural sources
of trust, given that business associates were also coreligionists if not relatives and shared
much more than the pursuit of profit alone). In keeping with this view, business
correspondence appears a traditional tool of commercial operations that limits market
expansion.
Historians who have called attention to the role of information in the business
organization of the past are generally more inclined than economists to acknowledge the
social and collective dimensions of reputation mechanisms. But they too by and large focus
on pre-established groups, whether family clans or religious and ethnic minorities. A notable
case is that of the Genoese merchant-bankers who dominated Iberian finances from the early
sixteenth to the mid seventeenth century.31 A finer example of the potential of business
correspondence as a historical source is Leos Müller’s study of two family firms of wholesale
traders in Stockholm, which demonstrates how intense communication of economic news and
social relations had a greater impact than legal enforcement on the stability of commission
trade. The activities of these Swedish merchants, however, were confined in terms of
geography, commodity and actors; hence the remarkable stability in their networks, which
revolved around a core of relatives in Amsterdam and a few occasional correspondents.32 The
exchange of economic information was also essential to the operation of numerous trading

diasporas that played an important role in disseminating skills and integrating distant markets
in various regions of the globe during the early modern period, such as the Sephardic Jews in
western Europe, the Mediterranean and the Americas, the Huguenots and Quakers in northern
Europe and the northern Atlantic, the Armenians in Persia, parts of Europe, the Levant, India
and Russia, the Indians in Central Asia, and later the Greeks in the Black Sea.
The geographical expansion of European commerce increased the need for
information to travel not only across vast geographical distances, but also across ethnic,
religious, cultural and political boundaries. In many of these instances, specialized groups of
brokers and trading diasporas became influential because of their ability to facilitate crosscultural trade.33 Their strength derived from their internal cohesion and geographical
dispersion, which gave them a competitive advantage over individual family firms. Received
traditions in the social sciences and the character of most historical records have induced
most scholars (whether proponents of a purely economic explanation of trust or inclined to
recognize its cultural components) to look primarily at how information circulated within the
boundaries of closed communities, situated either locally or globally. But precisely because
of their role as cross-cultural agents, trading diasporas had to engage in sustained economic
relations with outsiders. Business letters offer us a unique lens through which we can observe
the workings of these economic relations.
III. Business letters across ethnic and religious boundaries
Sephardic Jews were the most global and the most successful trading diaspora of the
early modern period and exerted particular influence on international commerce between

1650 and 1750.34 Their efficacy, especially in the Dutch Atlantic economy, was such that on
more than one occasion they learned of political or military news before diplomats did, and
with this news were able to influence the fluctuations of the Amsterdam stock exchange.35
They also continued to be dynamic actors in Mediterranean trade throughout the eighteenth
century. Information among Sephardim circulated orally and via private letters. Few
collections of such letters exist, perhaps none matching that of the 13,659 letters written
between 16 December 1704 and 4 February 1746 by the Ergas & Silvera partnership of
Leghorn (Tuscany) to both coreligionists and non-Jews in numerous ports of the
Mediterranean and Europe as well as Goa, the capital of Portuguese India.36 If smaller than
the largest existing sets of merchant letters, this corpus is an unusual, if not unique source
documenting the world of Sephardic merchants.
Leghorn was then the most thriving Mediterranean port after Marseille and the largest
Sephardic settlement in Europe along with Amsterdam. Ergas & Silvera was a prominent
merchant house, with a branch in Tuscany and one in Aleppo (Syria). Like many of their
coreligionists in Leghorn, Ergas & Silvera’s bulk of trade was with the Ottoman Empire, and
specifically the import of raw cotton from the Levant. They also re-exported raw silk from
southern Italy, funnelled fine silk textiles from Italy to central and northern Europe, and
traded in a large variety of Mediterranean goods. Unlike the Dutch and English Sephardim
who made their fortunes in the West Indies, those based in Leghorn were not directly
involved in commerce with the Americas, but controlled a large share of the imports to the
Italian peninsula of American goods, especially tobacco, sugar, indigo, coffee and Brazilian

wood. The additional specialty of the Sephardim of Leghorn was the exchange of
Mediterranean coral and Indian diamonds. From the 1660s, this lucrative and risky barter
came increasingly under the aegis of the English East India Company, and London became
the world market for rough diamonds.37 The readmission of the Jews to England in 1656
spurred this trade, which in turn stimulated new waves of Sephardic migration to London.
However, throughout the eighteenth century, and especially until the 1730s (when the English
lifted all restrictions on diamond trade and achieved supremacy in the Indian Ocean, and
when Brazilian diamond mines began to be exploited), the Sephardim of Leghorn continued
to carry out the exchange of coral and diamonds relying on a Portuguese connection centred
on Lisbon and Goa. Indeed, the latter remained the centre of diamond trade until 1730.38
Of the 13,659 surviving letters of Ergas & Silvera, 242 were addressed to Christian
(mostly Italian) merchants in Lisbon, and 86 to Hindu merchants in Goa. They all concern the
coral and diamond trade. In light of the diversity of these intermediaries and the lack of an
overarching legal authority to which any parties could bring their complaints (aggravated by
the ban of Jews from all Portuguese dominions), it is natural to wonder how it was possible
for trust to be built across such geographical and cultural distances. The answer, I believe,
lies primarily in the intense and widespread circulation of business letters among these
merchants, which created and nourished mechanisms of mutual obligations and reciprocal
control that worked even in the absence of formal enforcing institutions. Moreover, each
merchant was not a monad but a member of a larger community (which in the case of the
Sephardim had a diasporic dimension). Driven by the search for profit, individual merchants

also abided by collective social and normative codes of behaviour determined by their
communitarian organizations. The result was not a series of occasional transactions, but the
development of durable cross-cultural relations of mutual dependence in the context of
complex inter-group dynamics made possible by the circulation of information about
individuals’ and groups’ reputation. Ergas & Silvera invested in the Portuguese branch of the
exchange of coral and diamonds for a period of over thirty years, between 1710 (when their
first shipment of coral to Goa is recorded) and 1741 (when they regularly preferred London
and Madras to their previous destinations). They opted for the Portuguese connection because
they could count on merchant letters to help them create a niche in a pre-existing network of
correspondents in Lisbon and Goa, who also served other Sephardim of Leghorn and their
coreligionists in Amsterdam and London.
In Lisbon, Ergas & Silvera primarily relied on Genoese and Florentine merchants,
who were resident there and active in the trade with the Italian peninsula. The most reliable
among these correspondents were the Florentine Enea Beroardi (in partnership with Girolamo
Paolo Medici, also from Florence, until 1738) and the Ravara and Cambiaso families of
Genoa. In the early eighteenth century, these Italians in Lisbon no longer held the dominant
position that they had occupied during the early phase of Portuguese exploration and
conquest, but they were still influential, especially in the import of food stables and luxury
items from the Mediterranean and the re-export of Portuguese colonial goods to various
Italian states. Around 1730, an anonymous traveller to Lisbon noted that the English and the
Dutch were the most privileged foreign communities in town, but that the Italians had the
biggest commercial houses next to the English, and some of them alone handled a larger
volume of transactions than the entire French ‘nation’.39

Most of Ergas & Silvera’s letters sent to Goa were addressed to the Camotim family
(Portuguese for Kamat) who, like all their other agents, belonged to the Saraswat caste, which
was the leading native elite throughout the four and a half centuries when the city was under
Portuguese rule.40 In the 1730s, the Camotins were probably the richest family in Goa.41 And
from Ergas & Silvera’s correspondence we learn that they operated as a united clan,
concerned for the good standing of their members and the continued delivery of new orders
from Leghorn. Writing to Gopala and Fondu Camotim in January 1727, Ergas & Silvera
complained to them about the lack of return cargos and letters from their relative Nillea
Camotim. At the same time, they wrote Lazzaro Maria Cambiaso in Lisbon inquiring about
the opinion that his ‘friends’, recently returned from Goa, held of this Nillea.42 Ergas &
Silvera’s correspondence indicates that cross-checks worked to threaten negligent agents. It
does not mention cases of active expulsion from the network by reputation mechanisms,
although it allows us to examine the circumstances under which some names appeared and
disappeared from the pool of Ergas & Silvera’s agents. In his analysis of the documents
concerning the medieval ‘coalition’ of North African Jews, Greif finds very little evidence of

misconduct.43 Similarly, the heterogeneous network of Sephardic, Catholic and Hindu traders
in which Ergas & Silvera participated showed a remarkable level of conformity, which may
testify to the success of the pressure exerted by letter-writing.
Considering the nature of the coral and diamond trade, business correspondence
proved much more efficient than public sources of economic information. Leghorn was then
a centre of production and dissemination of economic information. A commodity price
current was first printed there in 1627 and exchange rate currents in 1663 (the latter became a
regular biweekly publication by the mid-eighteenth century).44 Moreover, every Monday,
Wednesday and Friday, the postal service delivered local and foreign mail, from which it was
possible to ascertain price variations elsewhere.45 Finally, numerous manuscript avvisi, which
included information concerning commercial activities, were sent to the Medici Grand Dukes
in Florence and widely circulated.46 We can presume that Ergas & Silvera made use of some
of these avvisi, and from their papers we gather that they subscribed to various gazettes, some
of which they sent to their partners in Aleppo, who eagerly awaited these publications in
order to catch up on world news.47 But private business correspondence was definitely their
primary source of information, especially concerning the organization of their long-distance
trade.

Despite the continued, though sporadic practice of face-to-face forms of silent trade,
including in the acquisition of diamonds in Persia,48 commission agency was the dominant
form of business association, and correspondence was the cement that enabled distant agents
to create solid webs across distant localities and wide cultural gulfs. Linguistic
comprehension was the prerequisite for communication. Most merchants were polyglot;
numerous specialized dictionaries were printed in Europe as aids to mercantile activities; and
commercial courts everywhere employed official translators with specific language
proficiencies. In the case under examination, the Sephardim of Leghorn wrote in Italian to
their agents in Lisbon and in Portuguese to their correspondents in Goa –in both cases
language was corrupted in its terminology, grammar and syntax, and most personal names
were translated and adapted. Language itself thus bears witness of the process of cultural
negotiations and translation in which these actors were involved.
The difficulty of bringing a lawsuit to court in a port that took months to reach and the
unpredictability that derived from the coexistence of various statutory and customary laws
conferred even greater importance on merchant letters, which were the only effective tools to
monitor the good standing of distant agents. As seen, this information travelled across local
or transnational merchant communities, and thus contributed vigorously to the formation of
cross-cultural trading networks. Nevertheless, the role of each community in implementing
conformity among its members should not be disregarded. For a minority group such as the
Sephardim, constantly susceptible to stereotypical anti-Semitic accusations of illicit
speculation, for example, collective credibility was an indispensable asset. In all merchant
communities more generally, peer pressure and normative sanctions concurred with rational
calculation in minimizing misconduct. In other words, self-policing mechanisms enacted by

each merchant family, community and diasporas were not distinct from the rational pursuit of
profit. Cross-cultural networks such as the one in which Ergas & Silvera participated should
thus be regarded as networks of communities, rather than as networks of individuals. Each
merchant involved in the exchange of coral and diamonds via Leghorn, Lisbon and Goa was
related to other members of the network by “multiplex relationships,” which were the source
of potential conflict as well as additional strength.49
The interconnectedness of the Sephardic diaspora across Europe was an essential
component in the stability of the cross-cultural network that included Italians and Hindus.
Notarial records both in Leghorn and Amsterdam reveal that the same correspondents who
served Ergas & Silvera in Lisbon and Goa also acted on behalf of several other Sephardim of
Europe.50 The interdependence of this diaspora was such that in 1722, upon hearing the news
of the seizure of the Portuguese ship Nossa Senhora do Cabo off the Mascarene Islands,
Ergas & Silvera initially feared that the diamonds that it carried would never be recovered
and lamented to a coreligionist in Genoa the suffering this loss would cause the Sephardim
both “here”, meaning in Leghorn, and in Amsterdam (‘que el Dio tenga piedad y restaure a
los perdientes que bastantes ai de nostra nacion aqui y Amsterdam’).51
The reliability of this inter-continental, informal network of Sephardic, Catholic and
Hindu merchants was so recognized and noteworthy that the Portuguese government
entrusted it with the transfer of public funds. After it lost the Northern Provinces of its Indian
territories to the Marathas (1736-1740), the crown appealed to Sephardic bankers for a loan

of about 90 million reis (the equivalent of 450,000 livres tournois) to finance its military
counter-offensive. The state bonds that were issued refer to ‘the money that is borrowed from
the merchants of the Portuguese Kingdom, Leghorn and Amsterdam’ (‘o dinheiro que se
toma por empréstimo aos mercadores do Reyno, Leorne e Amstardão’) –an expression that
clearly alludes to Portuguese New Christians and Jews. But the identity of these bankers had
to be protected from the Inquisition, and the money had to be made available in Goa. Once
more, it was the Italians of Lisbon and the Camotins of Goa who supplied the link to the
Sephardic diaspora. In 1742 Italian merchants like Enea Beroardi, Giovanni Battista Ravara,
Lazzaro and Gianandrea Cambiaso –all prominent members of the Italian community of
Lisbon and among Ergas & Silvera’s correspondents– bought these state bonds and thus
served as intermediaries in the repayment of sums in Lisbon.52
IV. Conclusion
On the basis of the records left by North African Jewish traders in the eleventh and
twelfth centuries, Avrom Udovitch maintained that, “Business letters were more than just a
means of communication; they served as sinews holding together the entire organic structure
of medieval Islamic long-distance trade…”53 The same conclusion applies to European
commerce, and not just during the Middle Ages. Despite the emergence of new economic
institutions (such as the chartered companies and the stock market) and the birth of so-called
economic journalism, letters remained the single most important source of information for
merchants involved in long-distance trade in the early modern period. This fact was intuited
even by Max Weber, who never failed to stress the precocious evolution of western

capitalistic institutions. Evaluating the importance of public information for the development
of a speculative market in Europe, Weber admitted that newspapers only began to play an
important role in the diffusion of economic information in the nineteenth century, when the
publication of stock prices became a rule, and concluded that “in the eighteenth century,
business depended on the organized exchange of letters”.54
The centrality of business letters persisted for several reasons. The relative weakness
of credit institutions, the minimal progress in transportation systems and the intrinsic
limitations of printed economic newspapers made the circulation of information among
private merchants a decisive tool to minimize the risks involved in agency relations (that is,
the relations between a ‘principal’ and his ‘factors’ and ‘agents’). Moreover, the
improvements in the legal validity of merchants’ records and the development of a
customary, internationally recognized commercial law did not eliminate the perils of
commission trade, especially when it was conducted outside familial circles. Correspondence
was simply more efficient than printed periodicals when it came to circulating information
about the aptitude and trustworthiness of private traders: and the circulation of this
information was what made commission agency viable. ‘One must take good account of the
types of people one deals with, or to whom one entrusts one’s good, for no man is
trustworthy with money’ – proclaimed the same anonymous Italian merchant of the
fourteenth century who had urged his fellows to tend with care to their correspondence.55 The
ability to provide and obtain information about the ability and past conduct of an agent was
the best way in which merchants could take action to reduce hazards in a world where
uncertainties loomed large and the means to tame uncertainties were restricted. In their
letters, merchants conveyed agreements of reciprocal assistance, promises of future profits,

and outrage about fraud. In so doing, they wove a net of legal and practical enforcing
mechanisms that could not otherwise have emerged.
If reputation was a merchant’s social capital, business letters were the most viable
channel though which to reinforce and spread it. Business correspondence thus served as an
instrument to control flows of information that were both a strategic economic advantage and
a form of social control. Both features were not necessarily confined to the limited world of
family firms or even trading diasporas, and merchant letters could become the connective
links between trading networks that transcended cultural barriers which are generally
presumed to jeopardize ‘natural’ mechanisms of reciprocity and trust. As evidenced in the
exchange of Mediterranean coral and Indian diamonds conducted by the Sephardim of
Leghorn via Lisbon and Goa, business correspondence was the glue that kept together a
network of communities who lived in distant regions and were separated by dramatic ethnic
and religious divides. While the prospect of future profitable transactions helped to contain
short-sighted opportunism and dishonesty, institutional coercion in many cases was feeble or
altogether absent. It was the regular and wide circulation of information, enhanced by the
global nature of the Sephardic diaspora, which created a set of durable and effective informal
mechanisms of reputation control that allowed cooperation to develop across geographical
and cultural borders.
